This must be the first instance of a Bluebird over the white cliffs of Dover :-)

Report from Birdguides:

After the stunning belated stories of Blue-cheeked Bee-eaters in Hampshire and Devon earlier this summer (both photographed, the Hampshire bird particularly nicely), hopes that one of them (if indeed two were involved) may still be bouncing around the country seemed to have faded away. It's been over three weeks since the sighting in North Devon. Then, out of nowhere, in the middle of the morning on 22nd, came amazing news from Kent: a BLUE-CHEEKED BEE-EATER had been found around Bockhill Farm, St.Margaret's-at-Cliffe. The bird was initially seen for some ten to fifteen minutes, then was lost for almost an hour. Just before noon, the bird was back and showed on and off (with at least one flight out to sea, the French coast clearly on view) until early afternoon. For those arriving from slightly further away than the southeast, there was a gathering sense of inevitability to the proceedings. The dogged old-timers working their local patch could enjoy the find of a lifetime.
